For convenience, and to show his sincerity, Winckelmann underwent conversion to the Roman Catholic faith, a move which horrified his Lutheran associates but opened to him a far wider field—of clerical contacts, of collections, of access of every sort—than he could ever have had as a mere Protestant neophyte, a naïve heretic in the Eternal City. Lutheranism would do nothing for a man whose obsession was with antiquity. Rome and its clergy could do everything. Winckelmann had no family ties that could impede a conversion to Catholicism. His beloved mother was long dead; his father had succumbed to epilepsy in 1750. Winckelmann also knew very well that, without firsthand contact with Rome, an immersion in antiquity far deeper than anything he could scratch together by looking at engravings in books, he would never win recognition as an Aufklärer, a wise and enlightening connoisseur. Expatriation or obscurity, go or die: there was no other choice, he would go to Rome. But before he went, he would write.
His first attempt at art criticism rested on wobbly foundations. Published in 1755, the year he left for Rome, Gedanken über die Nachahmung der grieschischen Werke in der Malerei und Bildhauerkust (Reflections on the Imitation of Greek Works in Painting and Sculpture) was his effort to enshrine ancient Greek art at the topmost and purest pinnacle of taste. It suffers, in retrospect, from the fact that Winckelmann at the time literally did not know what he was talking about. He had scarcely seen any Greek art; he had only read about it, and seen a few engravings. But this was also true of his own readers, and it made very little difference; the essay was an immediate success. One phrase from it in particular became a standard utterance in the presence of the Ideal, a motto of neoclassicism: the characteristic of high Greek sculpture was “eine edle Einfalt, eine stille Grosse”—“a noble simplicity, a calm grandeur.” This essay later became the basis of his most influential and elaborate work, his Geschichte der Kunst des Alterthums (History of Ancient Art, 1767).
Winckelmann was chiefly responsible for implanting the modern belief that later classical art, Greek and Roman, was a degenerate form of the “pure,” early-Hellenic tradition. There were no limits to his admiration for Hellas. “Our race is not likely to produce as perfect a body as the Antinous Admirandus, nor can our ideas conceive anything beyond the superhuman and harmonious proportions of a god as they have taken shape in the Apollo Belvedere. Here is the consummation of the best that nature, art, and the human mind can produce. I believe that imitating the Greeks can teach us to become wise more quickly … They have marked for us the utmost limits of human and divine beauty.” This, Winckelmann believed, was partly because the Greeks had achieved a sort of genetic transcendence, expressed in the “great care” they took to “have beautiful offspring.” They sought to avoid any distortion of their own bodies; Alcibiades “refused to play the flute in his youth because it might distort his face, and the Athenian youths followed his example.”
In the true and exemplary art of Greek antiquity, Winckelmann saw the refutation of much of his own age and its cultural expressions. Modern artists had gone off the rails, and the Baroque filled Winckelmann with disgust. Among his contemporaries, “especially the famous ones” (meaning the school of Bernini), admiration was reserved for “exaggerated poses and actions, accompanied by an insolent ‘dash’ that they regard as spiritedness.… Their favorite concept is ‘contrapposto,’ which for them is the essence of everything that makes for artistic perfection. They want their figures to have souls as eccentric as comets.” Since contrapposto—the depiction of a standing figure with most of its weight reposing on one leg—was an absolutely fundamental device of classical Greek art later than the archaic, one may well wonder what Winckelmann thought he was getting at.
Nevertheless, it was really Winckelmann who invented the idea of stylistic development within antiquity, a master story of rise and decline. He was also the first writer to create a sexual narrative within his subject. Winckelmann was homosexual—when his friend Casanova interrupted him in mid-grapple with a servant one Roman afternoon, he unconvincingly explained that he had undertaken this sexual adventure in the interests of research, since he wanted to know what it was that the ancient Greeks had liked so much. But his yearning, lip-smacking descriptions of the ideal Greek body obviously come from deeper sources; and his descriptions of the canon, in which (for instance) the left testicle is always larger than the right, are permeated with desire.
Unfortunately, his sexual passions not only supplied fuel for his art interpretation, they led to his death. In the spring of 1768, after a meeting with the Empress Maria Teresa in Vienna, he was passing through Trieste on his way back to Rome when his eye was caught by a pockmarked young hustler on the waterfront, by the name of Francesco Arcangeli. Winckelmann made the classic mistake of boasting to Arcangeli about his exalted friends in Rome, and showing him some valuable medals the empress had given him. They were both in Winckelmann’s room, number 10 in the comfortable Locanda Grande, when Arcangeli turned on Winckelmann, tried to choke him with a cord, and then repeatedly stabbed him.
Few sexual encounters between foreigners and natives in Rome had such drastic outcomes, but it need hardly be emphasized that prostitution was one of the most commonplace and visibly eternal aspects of the Eternal City. For the visitor, its very air was saturated with sex, offered, bought, paid for, and consummated. If you were male and could manage a trip to Rome without getting laid, this could only be because you did not want sex. The frequency with which tourists indulged their tender passions is certainly hard to gauge, since letters home do not always describe it—sex with Italian strangers, socially high or low, was not the first thing you would tell the family about—and diaries were often censored and tampered with by the travelers’ descendants. But the availability of Italian women—not only professionals, but more or less respectable married ones as well—was a well-known fact among English travelers. “If Italy don’t spoil his Chastity and Germany his Sobriety, I flatter myself he will preserve the character he sets out with, as an honest worthy young man,” wrote Sir George Oxenden of his son Henry (1721–1803). Few Grand Tourists could have been unaware of the major punishment of vice, death by venereal disease, or of the painful and usually ineffective treatments eighteenth-century medicine reserved for the pox. Among others, Charles Howard, Viscount Morpeth, succumbed to it in Rome in 1741 in his early twenties, necessitating a by-election in Yorkshire.
The perils of vice had been a well-known feature of Rome since antiquity, when prostitutes were called lupe or she-wolves, perhaps in homage to the original lupa who suckled Romulus and Remus, and brothels—particularly dense in the area of the city known as Suburra—were known as “lupanars.” We owe one of our commonest sex terms to the humble environment in which so many of the street girls traded; they offered sex out of doors, in the arches or fornices of the city; hence “fornication.”
